Face is concordant with valve seat upper surface, in order to install coil assembly.When valve opening, coil assembly is powered, and core iron 2 is attracted upwards, closes valve
When, coil assembly power-off, core iron 2 moves downward under the effect of core iron spring 13, while pilot valve needle 4 closes pilot valve mouth 22.
It explains below to the valve opening process of solenoid valve of the present invention:
When inlet outlet pressure differential is higher than P0When valve opening process:
Pilot valve is opened at this time, piston upper chamber pressure release, since inlet and outlet pressure difference is higher, causes piston upper and lower cavity pressure difference high
In the pressure value of pressure-control valve setting, so that pressure-control valve needle 8 be made to overcome the power of pressure-control valve needle spring 7 and transport upwards
It is dynamic, big balance hole 23 is opened, realizes the pressure release of piston upper and lower cavity, piston element can not move upwards, and main valve is still within closing
Then state, fluid cross nut 9 and flow to piston upper chamber, another way again by big 23 feed pressure control valve pin hole 25 of balance hole
Piston upper chamber is flowed to by small balance hole 24 and nut 9, then by the outlet of the flow direction of pilot valve mouth 22, this is that process is pressure release
Journey；
With the unlatching of pilot valve, inlet and outlet pressure difference is slowly reduced to setting value P0Hereinafter, piston upper and lower cavity pressure difference at this time
Power be also reduced to setting value hereinafter, to pressure-control valve needle spring 7 effect be greater than pressure-control valve needle 8 suffered by difference force,
Pressure-control valve needle 8 is moved downward, big balance hole 23 is closed, fluid tight passes through small balance hole 24 at pressure-control valve needle at this time
Piston upper chamber is flowed to, effective throttling is realized, it is ensured that piston upper and lower cavity pressure difference, since inlet outlet pressure differential is smaller, piston
Downward difference force suffered by component reduces, and upward difference force is higher than downward difference force, to realize piston element by upward
Resultant force, thus realize main valve open.
The above are pressure differences to be higher than P0When by first open pilot valve pressure release, when pressure difference drops to setting value, realize main valve open
It opens, to substantially reduce the fluid impact noise opening main valve directly under High Pressure Difference and generating.
When inlet outlet pressure differential is lower than P0When valve opening process:
Because inlet outlet pressure differential is less than setting value P0, when pilot valve is opened, piston upper chamber pressure release, piston upper and lower cavity pressure difference
It increases, fluid controls small balance hole 24 at needle by pressure port and throttles, and piston upper and lower cavity pressure difference is opened less than pressure-control valve
The setup pressure value of pressure-control valve needle 8, therefore pressure-control valve needle 8 will not move upwards, the at this time upward pressure of piston element
Poor power is greater than downward difference force, and piston element moves upwards therewith, to realize that main valve is opened.
The above are pressure differences to be lower than P0When opening process, this process is consistent with common guide electromagnetic valve opening process, because
It is acceptable for itself commutation action noise under low voltage difference, be not necessarily to specially treated, it is ensured that solenoid valve under low voltage difference valve opening reliably and
Response rapidly, only when pressure difference is excessively high, opens the function of main valve after the first pressure release of realization when blade inverting fluid noise can generate obvious harassing and wrecking
Can, realize the reduction of commutation noise.And setting value P0Setting can be adjusted according to the requirement of not homologous ray, can match different
System and different maximum noises require to be adjusted, and maximize and realize that the part under different demands is general.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to attached drawing and interior described in specific embodiment above
Hold.Any modification without departing from function and structure principle of the invention is intended to be included in the range of claims.
